    • A 1,1,1,3,3,3-hexafluoropropane product of greater than about 99.9 weight percent purity containing less than about 100 parts per million unsaturated fluorocarbons and a method for its purification from a distillation mixture of 1,1,1,3,3,3-hexafluoropropane with at least one unsaturated fluorocarbon which method includes the steps of: a) reacting the mixture with chlorine to saturate the unsaturated fluorocarbons, b) washing the reacted mixture with an aqueous solution to remove residual hydrochloric acid and chlorine, c) removing the aqueous solution, and d) distilling the reacted mixture to obtain a 1,1,1,3,3,3-hexafluoropropane product of greater than about 99.9 weight percent purity containing less than about 100 parts per million unsaturated fluorocarbons.
